[Feel Zhou]

Hello, my friend
This is tom, I'm sending my greeting from China.
My customer send mail via my postfix server
main.cf
    mynetworks = hash:/etc/postfix/mynetworks_table
/etc/postfix/mynetworks_table
    ip1 PERMIT
    ip2 PERMIT
Today, one of my customer send mail via the new ip.
And this new ip not in the /etc/postfix/mynetworks_table
Can you help me to resolve it.
Thanks for your time.
Tom
